Toolardo Cheminformatics

Toolardo Cheminformatics is a free, browser-based collection of tools for chemical structure drawing, visualization, molecular file conversion, and exploratory analysis. It includes an interactive 2D molecule sketcher, SMILES viewing and validation, 3D conformer generation, molecular structure visualization, and conversions between SMILES, SDF, MOL2, PDB, and XYZ formats. Additional utilities support exact SMILES deduplication, salt and fragment extraction, and approximate FTIR, UV-Vis, and NMR spectrum prediction. Supported calculations and file operations run locally in the browser without requiring registration or uploading molecular structures to the Toolardo server. Generated structures and predicted properties should be independently validated before scientific use.
